1. What is ONU?
ONU refers to optical network unit. It is the optical terminal device in the fiber access network, which provides users with multiple service interfaces. The network side of ONU is the optical interface. As for the user side, it’s the electrical interface. Therefore, ONU can transmit optical signals into electrical signals and vice versa. Besides, it’s capable of converting voice signals of D/A and A/D, reusing, processing signals and maintenance management.
